8. Quarterbacks

New York boasts four quarterbacks on its current roster (Mark Sanchez, Geno Smith, Greg McElroy and Matt Simms), but none seem to be capable of being a franchise signal-caller.

Sanchez, the team's starting quarterback the last four seasons, has struggled mightily, as he has compiled just a 71.7 career passer rating and led the Jets to two straight non-playoff seasons.

McElroy and Simms, on the other hand, simply are nothing more than backup quarterbacks.

Smith possesses the most upside of the quartet, but the rookie struggled with accuracy and troubles with the media throughout minicamp, and there are concerns about his ability to adjust to the NFL-level.

It's any guess who will start the season as New York's quarterback, but its almost certain that the positional unit will struggle.

7. Wide Receivers/Tight Ends

Drops, injuries and lack of big-time playmakers have haunted New York's receiving corps in recent years, and the unit enters this upcoming year weaker than ever.

Santonio Holmes, the team's No. 1 wideout and only true proven weapon, is a question mark to begin the regular season. No. 2 receiver Stephen Hill still hasn't overcome the drops and injuries that derailed his rookie season.

Clyde Gates and Ben Obomanu, while solid NFL players, cannot be relied upon as anything more than decent backups.

As for tight end, the loss of Dustin Keller could sting badly.

Jeff Cumberland showed promise last season, but he isn't ready to be a staple in the team's offense, and Kellen Winslow is a long way away from returning to his Pro Bowl form, as he recorded just one catch last season.

Unless unproven players such as Jordan White and Hayden Smith step up big time, the receiving corps will compete with quarterback as the Jets' weakest positional unit.
